Ssomeguyanswered grow question 5 years ago No,2 doesn't look like an auto to be honest, nice hybrid look though. Looks similar to a white widow I once saw.
No,3 looks awesome, like bloodyskunk/lsd/meth.

Truth is, you cannot say what strain it actually is by looking at it. A lot of strains have certain leaf/bud look, grow traits, smells potency and taste.
